Police News Affairs Officer John Mirabelli said 172 pounds of the hallucinogenic material with a street value of about $1.2 million were found inside a building and police are hunting for the recipients, distributors and whoever sent it to Chicago.

Other than "earlier this month," police refused to say where or when the drugs were found.

“They intercepted the shipment,’’ Mirabelli said of the narcotics officers who were acting on a tip when they found nine silvery bundles with the leafy substance.

A search warrant was obtained and the packages, which have colorful stickers on them, including ones with Batman's foe the Joker emblazoned on them, were found, said Mirabelli.

Additional packages displayed a monkey holding a banana labeled with the words “Monkey Spanker,” according to a police statement.

“The labels attract young children,’’ Mirabelli said.

An Illinois State Law was passed early last year banning the sale of synthetic cannabis and products containing hallucinogenic substances, the statement said.

Police today displayed the seized material, but said as of Wednesday night no one has been arrested.
